Because our Tumblr followers and FB fans demanded it so often -- Sylar finally got a chance to be Loki from the Avengers.

Of course, none of it would be possible without *Riku-Ryou's kindess to let us borrow her stunning Loki cosplay. Please go giver her some love, she deserves if for such an amazing craftsmanship costume!

No in the uh... movie... version his eyes are still green. Tom Hiddleston has naturally green eyes, but the hue changes depending on the light. & I suspect they're especially blue in the Avengers movie is because of the influence of the tesseract. Otherwise, canonically they're green. See : [link]

There's some speculation that in Avengers, Loki's eyes are blue because he is also controlled by the scepter he uses to control Hawkeye and Erik Selvig, as their eyes also turned blue after Loki uses the scepter's magic on them.

I don't know if this is true, but it could be. Anyways, we'll hopefully get to know more about this in Thor 2. Can' wait for that movie ^^

...loki's eyes, in original norse mythlogy, are green. it is true, he came from the Jontuns (ice trolls, and stuff) wich, yes, turns him into a frost being, and yes, I assume the scepter changes his eyes blue, but they have always been green. always.
